scan-nest-features

Source-aware scanner for the NestJS surfaces zod-nest depends on. Three packages collapse into one scanner because they evolve together: @nestjs/swagger provides the OpenAPI bridge, @nestjs/common provides the runtime contracts (pipes, interceptors, decorators), and @nestjs/core provides the introspection tools (DiscoveryService, Reflector).

When to invoke

• As part of /check-upstream-updates --target nest|all. The orchestrator hands off; this skill returns findings.
• Standalone after a Nest major or minor bump. The plugin emit and metadata-factory shape are the highest-risk areas — verify them.
• When debugging a Nest-integration issue — e.g. a controller's @ZodResponse doesn't show up in the doc. The scanner shows whether the explorer / discovery API still works the way we assume.

Inputs

Optional:

• --package swagger|common|core|all — narrow the scan. Default all.
